Food baking machine
View Patent ↗A food baking machine includes a heating device. The heating device includes a lower hot plate on a lower side of the heating device, a rotatable and vertically slidable upper hot plate on an upper side of the heating device, a rotatable connecting member for connecting the lower hot plate and the upper hot plate and a sliding member. The upper hot plate is slidably connected to the connecting member and fixes its position thereunto by the sliding member. The upper hot plate is rotatable connected with the sliding member. The upper hot plate and the lower hot plate are connected to power supply separately. The connecting member includes a first connecting segment, a second connecting segment and an axle. The second connecting segment is rotatable connected to the first connecting segment by the axle.

the connecting member comprising a lower upright connecting segment, an upper upright connecting segment and a rotating axle; and the upper upright connecting segment being rotatably connected to the lower upright connecting segment via the rotating axle, the upper upright connecting segment being rotatable between a vertical position where the upper upright connecting segment is in vertical alignment with the lower upright connecting segment and a horizontal position where the upper upright connecting segment is disposed above and parallel to the lower hot plate;
wherein the upper hot plate is parallelly moveable with respect to the lower hot plate when the sliding member slides on the lower upright connecting segment and the upper upright connecting segment;
wherein the upper and lower hot plates are flat plates made of glass ceramic, and adopt single or multiple layers of nano-thickness of heating coating; and
wherein the height of the lower upright connecting segment is equal to total thickness of the upper and lower hot plates, and the sliding member is adapted to slide downwards to the lower upright connecting segment such that the upper hot plate is rested on top of the lower hot plate, and then the upper upright connecting segment is adapted to rotate downwards to its horizontal position such that the upper upright connection segment is rested on top of the upper hot plate.
2. The food baking machine as claimed in claim 1 , further comprising an electric control device adapted to drive the slide of the sliding member and the rotation of the upper hot plate, a timer controller electrically connected with the upper and lower hot plates for setting and controlling heating time, and a temperature monitoring and controlling system electrically connected with the upper and lower hot plates for setting and controlling heating temperature.
3. The food baking machine as claimed in claim 1 , wherein the food baking machine is configured to be folded into a compact structure with a thickness not exceeding about 50 mm.
4. A food baking machine comprising a heating device, the heating device comprising:

the upper hot plate being slidably connected to the connecting member and having its position fixed thereunto by the sliding member,
the upper hot plate being rotatably connected with the sliding member and rotatable upwards to a vertical position perpendicular to the lower hot plate or downwards to a horizontal position above and parallel to the lower hot plate,
the connecting member comprising a lower upright connecting segment, an upper upright connecting segment and a rotating axle; and the upper upright connecting segment being rotatably connected to the lower upright connecting segment via the rotating axle, the upper upright connecting segment being rotatable between a vertical position where the upper upright connecting segment is in vertical alignment with the lower upright connecting segment and a horizontal position where the upper upright connecting segment is disposed above and parallel to the lower hot plate;
wherein the upper hot plate and the lower hot plate are flat plate; and the upper hot plate and the lower hot plate are made of heat-resistant material; and
the food baking machine further comprising an electric control device, which is used to drive the slide of the sliding member and the rotation of the upper hot plate;
wherein the upper hot plate is parallelly moveable with respect to the lower hot plate when the sliding member slides on the lower upright connecting segment and the upper upright connecting segment;
wherein the upper and lower hot plates adopt single or multiple layers of nano-thickness of heating coating.
5. The food baking machine as claimed in claim 4 , further comprising a timer controller and a temperature monitoring and controlling system, the timer controller and the temperature monitoring and controlling system is electrically connected with the upper hot plate and the lower hot plate to set and control the heating time and temperature.
6. The food baking machine as claimed in claim 4 , further comprising a timer controller or a temperature monitoring and controlling system, the timer controller and the temperature monitoring and controlling system is electrically connected with the upper hot plate and the lower hot plate to set and control the heating time and temperature.
7. The food baking machine as claimed in claim 4 , wherein the heat-resistant material is glass ceramic.
